MOVED: Working whilst traveling

I'm currently planning a trip to Central America in mid-October of this year, I am planning to travel through all seven of the countries of the region and have given my self a budget of £600 a month ($950), as this would be my first experience traveling, my question is would this be enough a month, im not looking to travel in luxury, I quite like the idea of a budget trip, hitching hiking around, using the local buses and cheap coaches as travel. I'm looking to be traveling for 3 months minimum, but ideally as long as possible.

I also like the idea of doing odd jobs to earn a free meal, or a free nights sleep, experiencing a much more rual and 'off the beaten track' side of the places im visiting. Is this sort of thing possible?

Any thoughts, comments or advice would be appreciated.
